Does tea go bad? How long does it last?
Aug
This is a classic scenario when organizing a cupboard. You find a half-empty box of verbena, a package of green tea brought back from a trip—the expiration date was eight months ago—and your instinct is to throw it away. Nine times out of ten, that’s pure waste: French regulations are perfectly clear on this point, and they’re on your side. Let’s take a look at what the law says, what actually goes bad in aging tea, and how to store your blends so they stay delicious for as long as possible.
What the regulations say: Tea has a "best-by" date, not an "expiration" date
It all starts with a distinction that many consumers confuse, and that French authorities explain in black and white. The DLC (best-by date, «best before») applies to highly perishable fresh products: meat, fish, and yogurt. This date is mandatory—there’s no room for debate. The DDM (minimum shelf life, «best before») applies to dry and non-perishable products: pasta, rice, canned goods… and your teas and herbal teas.
However, as indicated in the’ANSES, consuming a product after its best-by date poses no health risk: the food may simply lose some of its flavor. The DGCCRF makes the same point: as long as the packaging has not been tampered with, a food item whose best-by date has passed can be consumed safely. It is in this spirit that the 2020 anti-waste law allows manufacturers to add the statement «This product can be consumed after this date» next to the best-by date.
In practical terms for your pantry: the date printed on your tea package is a guideline for optimal quality set by the manufacturer—not a strict safety deadline. Tea that’s been «past its expiration date» by a few months—as long as it’s been stored in a dry place in its original packaging—is still safe to drink. It might just be a little less flavorful—that’s all.
What Really Deteriorates in Tea as It Ages
While safety isn’t at stake, flavor does have a shelf life. Tea and herbal teas consist of volatile aromas trapped within dried plant material: over time—and especially when exposed to air—these aromas slowly evaporate. The flavor becomes flat, the floral notes fade, and the fruity notes disappear. The most delicate profiles (green teas, scented teas, delicate flowers) lose their intensity more quickly than robust and spicy profiles, whose dense flavors hold up over time. This is why the best-by date set by each manufacturer varies from product to product: rely on the date printed on your package rather than on generic charts found online.
The most reliable test is still your nose: open the box and take a whiff. Tea that’s still good gives you a clear indication right away. Stale tea smells like… not much. And here’s a foolproof tasting clue: tired tea leaves yield a pale first cup and don’t hold up for a second, whereas fresh, whole leaves hold up very well when you steep several times.
The 5 Enemies of Your Teas and Herbal Teas
Enemy No. 1. Every time you open a package, the aromas escape: the more airtight the container is and the better it fits the remaining amount of tea, the longer the tea will last.
The only truly dangerous enemy: dry plants that absorb water can develop mold. Never leave a wet spoon in the box, and never store the kettle on top of the cupboard.
The pretty glass jars on the shelf make for great photos but lousy tea: the light fades the colors of the plants and dulls their scents. Always use an opaque container.
It speeds up the aging process. Keep teas away from the oven, stovetops, and sunlight coming through the window: a cool, dry cupboard is more than enough.
Dried herbs are like sponges for flavors: when stored next to cumin or coffee, they eventually take on those flavors. We set aside a special spot just for them.
The Simple Method for Perfect Preservation
No lab equipment needed. A opaque, airtight container (metal or ceramic with a seal), arranged in a dry, temperature-controlled storage area, away from heat sources and spices: that’s the main thing. For bulk items, transfer the opened package to a container that fits the amount rather than leaving the remaining contents of the bag exposed to a large volume of air. For tea bags, keep them in their original, sealed box—it was designed for that purpose. And the refrigerator? Not a good idea for everyday use: every time you open the door, condensation forms on the cold tea leaves, and you’re back to enemy No. 2.

The best way to reduce waste is to buy just the right amount. It’s better to buy a package that you’ll finish in two months than to have a stockpile that goes bad over two years: adjust the quantities to your actual consumption, even if that means reordering more often. This is also a factor we consider when selecting Tea and herbal tea brands that we carry: well-designed packaging that protects the product right down to the last cup.
The only time you really need to throw it away
Let’s be thorough, because the rule «the best-before date is not a safety limit» comes with one condition: proper storage. If your tea has absorbed moisture (musty smell, clumped leaves, whitish or fuzzy spots), there’s no question about it—throw it out: moldy tea leaves can’t be salvaged, even with boiling water. Same rule applies if food moths have gotten into the package. Aside from these cases, which are related to storage rather than the date, your forgotten tea deserves a chance: use a slightly larger amount, steep it for one more minute, and judge it by the cup.
FAQ: Expired Tea and Storage
Can you drink tea that's past its expiration date?
Yes, as long as the package is intact and has been stored in a dry place. Tea has a “best-by” date, which indicates the date by which the product is at its best, not a safety deadline: ANSES and the DGCCRF confirm that a product past its “best-by” date is still safe to consume, although the flavors may be less intense.
What is the difference between DLC and DDM?
The «Best Before» date is a mandatory safety limit applicable only to highly perishable fresh products. The «best before» date is a quality indicator: after this date, the product may lose some of its flavor but remains safe to eat as long as the packaging is intact. Teas and herbal teas fall under the “best before” category.
How can you tell if tea has gone bad?
Start with the nose: a fresh tea smells wonderful as soon as you open it, while a stale tea has almost no scent left. In the cup, tired leaves produce a pale, weak infusion. And at the slightest sign of moisture (a musty smell, stuck-together leaves, suspicious spots), throw it away without hesitation.
Should you store tea in the refrigerator?
Not for everyday use: every time you bring them in from the cold, condensation forms on the leaves, and moisture is actually the worst enemy of dry plants. A dry, temperate closet away from light is much better suited for this purpose.
What's the best way to store loose-leaf tea once the package is opened?
In an opaque, airtight container—made of metal or ceramic—that is sized to fit the remaining quantity, to minimize the amount of air in contact with the leaves. Avoid glass jars exposed to light and large, nearly empty containers where the tea loses its flavor.
